Ultomiris (ravulizumab) has been recommended for marketing authorisation in the European Union (EU) for the treatment of adult patients with neuromyelitis optica spectrum disorder (NMOSD) who are anti-aquaporin-4 (AQP4) antibody positive (Ab+). If authorised, Ultomiris would be the first and only approved long-acting C5 complement inhibitor for the treatment of AQP4 Ab+ NMOSD in the EU.
The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency based its positive opinion on results from the CHAMPION-NMOSD Phase III trial.1 In the CHAMPION-NMOSD trial, Ultomiris was compared to an external placebo arm from the pivotal Soliris PREVENT clinical trial.
Ultomiris met the primary endpoint of time to first on-trial relapse as confirmed by an independent adjudication committee. Notably, data showed zero relapses were observed among Ultomiris patients with a median treatment duration of 73 weeks (relapse risk reduction: 98.6%, hazard ratio (95% CI): 0.014 (0.000, 0.103), p<0.0001), and continuing through a median duration of 90 weeks.1
